Do you think 1/128 microstepping offers any significant advantages over 1/16?
From what I have seen on videos, its more about smoothness of movement than resolution. With 128th your basically making the steppers run in a fluid motion and reducing jerk. The problem right now with ramps 1.4 and specifically delta printers is that you really tax the cpu. If you have a full graphics display, a large delta printer and anything over 1/16th you are basically running out of resources. On my particular setup, running marlin FW and the discount LCD it prints fine on my large delta printer, but the jog dial is a bit unresponsive when printing and trying to make speed adjustments or temp adjustments on the fly. The CPU seems taxed enough just during the print. Also anything over 300mm/s seems to throw the printer into a frenzy on my setup. Even homing is a problem over 300mm/s. I suspect the mega R3 I have is not powerful enough or my motors are running out of torque.
